Jin Yao 61415418cd perf annotate: Fix broken arrow at row 0 connecting jmp instruction to its target
commit 80f62589fa52f530cffc50e78c0b5a2ae572d61e upstream.

When the jump instruction is displayed at the row 0 in annotate view,
the arrow is broken. An example:

 16.86 │   ┌──je     82
  0.01 │      movsd  (%rsp),%xmm0
       │      movsd  0x8(%rsp),%xmm4
       │      movsd  0x8(%rsp),%xmm1
       │      movsd  (%rsp),%xmm3
       │      divsd  %xmm4,%xmm0
       │      divsd  %xmm3,%xmm1
       │      movsd  (%rsp),%xmm2
       │      addsd  %xmm1,%xmm0
       │      addsd  %xmm2,%xmm0
       │      movsd  %xmm0,(%rsp)
       │82:   sub    $0x1,%ebx
 83.03 │    ↑ jne    38
       │      add    $0x10,%rsp
       │      xor    %eax,%eax
       │      pop    %rbx
       │    ← retq

The patch increments the row number before checking with 0.
